I am creating a program to store Categories and SubCategories
like main category is having subcategories and each subcategory can have subcategories like a heirarchy.
Main Category1 | | Sub Category1 Sub Category 2 | Sub Category 1a
I want to store this heirarchy structure in a collection can anybody explain which type of collection to use and how will i retrieve the collection.

With my understanding about your problem statement i suggest you can use HashMaps where a Key,Value pair could be <MainCategory,SubCategory> Where the SubCategory is of type HashMap. That means you will result in something like this.
like this. Still not clear. Take a look at this snippet.
